実験手順: Sodium hydride (101.5 mg, 2.33 mmol) (55% in paraffin liquid) was added to a solution of 249 mg (1.16 mmol) of the title compound produced in step (i) of Reference Example 7 in N,N-dimethylformamide (2.5 ml), and the mixture was stirred at room temperature for 30 min. Thereafter, methyl iodide was added, and the mixture was stirred at room temperature for 1 hr. The reaction was stopped by adding a saturated aqueous sodium hydrogencarbonate solution, and the reaction solution was extracted with ethyl acetate. The organic layer was washed with water and saturated brine in that order, was dried over anhydrous sodium sulfate, and was filtered. The filtrate was concentrated under the reduced pressure, and the residue was purified by column chromatography on silica gel (hexane:ethyl acetate=2:1) to give 239 mg (yield 90%) of the title compound. the mixture was stirred at room temperature for 1 hr the reaction solution was extracted with ethyl acetate The organic layer was washed with water and saturated brine in that order was dried over anhydrous sodium sulfate was filtered The filtrate was concentrated under the reduced pressure the residue was purified by column chromatography on silica gel (hexane:ethyl acetate=2:1)

実験手順: 4-bromoacetanilide (1.0 g, 4.67 mmol) in DMF (5 mL) is added dropwise to a suspension of sodium hydride (224 mg, 5.61 mmol, 60% dispersion in mineral oil) in DMF (5 mL) at 0° C. After stirring 1 h at 0° C., iodomethane (349 μl, 5.61 mmol) is added and the reaction mixture warmed to RT and stirred 16 h. The reaction is quenched with water (15 mL) and extracted into EtOAc (3×15 mL); the combined organic phases are then dried over Na2SO4 and reduced in vacuo. Purification by column chromatography (40% EtOAc in heptane) gives the title compound. the reaction mixture warmed to RT stirred 16 h The reaction is quenched with water (15 mL) extracted into EtOAc (3×15 mL) the combined organic phases are then dried over Na2SO4 Purification by column chromatography (40% EtOAc in heptane)
